Yes, Jessica Simpson is still pregnant, and she looks like she’s going to be active until the bitter end. She appeared on “The Tonight Show” last night to promote her new series “Fashion Star,” and she looked like she was carrying quintuplets (as far as we know, there’s only one kid in there). Jess and Jay Leno joked about her Elle cover that paid tribute to Demi Moore‘s classic Vanity Fair cover and the fact that she’s feeling labor pains when she’s not in labor.

She also talked about the nickname that she and John Varvatos came up with for her on the set of “Fashion Star,” mainly having to do with Jess’ use of Spanx and how hot things are in the studio. We’ll let Jess describe her not-very-dainty nickname, which describes an affliction we’ve all suffered from at one time or another.
